Hello Kaling,
I bought DWE when Eunice was around 8months old. It is realy expensive. I bought it because it is systmetic and it got training for my philipiano. I am a working and lazy mum
Most of the time, Eunice will be with my philipino, so it is important to give something for them to do. DWE had a well organised system and time table for them.
I also got some VCD of Barney and Elmo. Eunice loves Barney and Elmo very much. She can sing along and follow some movement. So. I think you should find something 浩謙 also like to watch, it will be more efficient learning.
Recently I am intersted in a set of DVD called 'your baby can read' . I will tell you whether it is good or not when I got it.
